Natural larvicides can be effectively used if part of a regular treatment program. There are a few naturally occurring bacteria that cause significant digestive problems for mosquito larvae without causing damage to other animals and plants. The primary bacteria used in larviciding are Bacillus thuringiensis israelensis (Bti) and Bacillus sphaericus (Bs). These are pretty effective in mosquito larvae through the first three stages of mosquito development. Once they transform to Pupae, the bacteria are not effective. Other natural larvicide controls include the fungus Lagenidium gigantem, the parasitic meatode Romanomermis, and fish.

For places where standing water cannot be eliminated, Mosquito Me Not provides an organic larviciding treatment. We use a blend of Bacillus thuringiensis israelensis (Bti) and Bacillus sphaericus (Bs).
